Applicantsflied December 1a, 19 4. Serial No. 755,094.

To all whom it may concern: Be it known that I, Farina Dr. James, a citizen of the United States,,and.

resident of El Centro, in the,county of -Im'- claimed.

An object of the invention is theprovision of a metal binding strip which aflords facilities for securing wire or other fabric to a frame or like support so that the fabric I will be effectively prevented from slipping or sagging from a desirable position in respect to the frame or like support.

A further object of the invention is the provision of a metal binding strip which can be quickly and easily applied to a frame for the purpose of securing fabric to the frame.

A further object of the invention is the provision of a metal binding strip of the character described which when in applied position on a screen or like frame serves not only to attach wire or other fabric to the frame in the manner of nails or like attaching devices but also serves to clamp the fabric to the frame in the manner of the usual strip of molding.

Other objects and advantages will be a parent from the following description, considered in conjunction with the accompanying drawings, in which Figure 1 is a fragmentary perspective view showing a metal strip embodying the invention in position to secure a wire fabric to a frame member.

Figure 2 is a plan view of the metal strip disposed with the fastening projections thereof uppermost.

Figure 5 is a fragmentary vertical section through a frame member, a piece of wire fabric, and a modified form of binding strip in position to secure the piece of fabric to the frame member. 7

. As is well known, wire or other fabric ordinarily is secured to a wooden frame or like support by means of tacks which are driven through the fabric at intervals along the support to attach the fabric to the suppiece of fabric so attached to a support will sag between adjacent nails or like fastening devices and a piece of fabric so attached to the support is very readily torn loose from the support, particularly when the tacks have been driven through the fabric adjacentto an edge thereof. It has been customary prior to my invention to make use of strips of molding in conjunction with the tacks or like fastening devices to secure fabric in place on a frame or to a like support, the molding being tacked to the frame or like support over the heads of the tacks and serving to aid the tacks in holding the fabric in place. My invention provides a strip which combines in one member projections adapted to be driven through fabric into a frame member or like support and an elongated body which carries the projections and will be'in position when the pro ections have been driven into the frame member or like support to clamp the fabric to the frame member or like support'in somewhat the same manner as a strip of molding, such as it has been the usual practice to provide prior to my invention. However, the projections and the binding body of the strips which my invention provides obviously will more effectively secure the W fabric to a screen frame (or like support) so that the fabric is not ermitted to sag or stretch between the mem ers of the screen frame or like support than is possible with theuse of separate parts and molding strips, as will be understood from the .following description. I

A metal binding strip embodying the invention as illustrated in Figures 1 to 4 inelusive is formed of'a strip of metal having substantially parallel longitudinal edges, such strip being folded along lines which extend longitudinally of the strip,the folded over portions of the strip being bent out- I ings 3 for the reception of nails, as at 4,

or like fastening devices, whereby the body of the strip will be clamped closely against a support 5, which may be a rail member of a frame for supportin a sheet of wire fabric 6, when the fastening projections 2 of the strip have been projected throu h the fabric into the support 5 until the b0 y,

of the strip presses the underlying portion of the fabric flatwise against the support.

In actual practice, the fastening projections 2 will be formed to be approximately the same size at their bases as the openings of a sheet of wire fabric through which they will-be projected, whereby the wires which define the openin s-of the wire fabric will strip be firmly clampe between the body of the and the sup ort into which the rojections have been riven, whereby the fa ric will be held securely against sagging or.

slipping from a desired position 1n respect to the support.

In the form of the device exhibited in Fig. 5 an elongated strip 10 of metal is bent a ong lines extending longitudinally thereof to provide a pair of inwardly extending aligned flan 'es 11 which connect and ner e the longitu inal ed e ortions of the strip with and in to the thereof. The outturned and at ri ht ang es to the flanges 11 and are serrate to provide the rows of pointed teeth as in the case of the form of the strip which is illustrated in Fi res 1 to 4 inclusive and has been herein fore described. The

body of the strip 10 is curved arcuately between the line of its juncture with the flanges or connecting portions 11. A-s ace thus is defined between the inner wal s of the connecting portions 11 and the remaining portion of the body of the strip. This space may be filled by a filler member 12. The 0 eration of the form of the device exhibit in Figure 5 is identical in essential respects with that of the form of the device exhibited in' Figures 1 to 4 inclusive and is thought to require no description. herein. 1

While each of the embodiments which I have illustrated and described is formed ortions o the strip 2 extend to provide two parallel rows of substantially V-shaped fastening projections, it will be obvious that a greater or less number of rows of fastening projections may be provided on the body of the strip without de /I0 parting from the spirit and scope of the invention. Moreover, the pointed projections 2 may be formed in any suitable known manner from a strip of metal, may be spaced apart as desired and may have any desirable length within a considerable range and be of any desirable configuration in cross sectional contour to meet particular conditions. When two or more rows of pointed projections are provided on the body of the I strip, the respective projections of adjacent rows need not be disposed in staggered relation as shown in the drawings but corresponding projections can be disposed in transverse alignment with each other. The material of which the strips and projections on the'body thereof is formed should be of material possessing sufficient rigidity to prevent indlvidual projections from turning laterally under the impact of a blow on the outer face of the body of the strip for the purpose of drivin the projection into a frame member or like support.

The outerfaee of the body of the strip may be ornamented in any suitable known manner to adapt the strip for use in upholsterin work in which an ornamental stri is esired.

O viously, my invention is susceptible of embodiment in forms other than those illustrated in the accompanying drawings and I therefore consider as my own all such modifications and adaptations of the .forms of the device herein described as fairly fall within the scope of the appended claims.
